    Could be a sign the injector filter is getting blocked? Only takes a very tiny amount of dirt to block this. It gets in every time the fuel hose is disconnected from the tank and reconnected again.
    See my thread on this from a few years back.

    Took my bike up to Mammoth @8000 ft plus. Had a bog off idle. Reset TPS and back in business.
    2012 TE 310 w/TXC ECU and 12 pt. Injector. Adjusting CO was not productive until TPS reset. Will ride later and add any experience or changes. Set at 105, 103, 100 I think. Also upped idle to just under 2000

    ETA I also brought my VW buggy up here with a new 1600 engine.. Solex/Baroso Carb. Ran like crap. Local guy Mike (Alpine Garage..has a Meyers Manx ) adjusted timing (advanced) adjusted carb and cleaned plugs and it runs fine now.
